KNITTING-MACHINE NEEDLE.

Specification of Letters Patent.

Patented June 5, 1906.

Applicati fil d January 27,1905. Serial No. 242,960.

To all whom it may concern.-

Be it known that I, EDWARD H. STURTE- VANT, a citizen of the UnitedStates, residing at Franklin, in the county of Merrimack and State ofNew Hampshire, have invented a certain new and useful Improvement inKnitting-Machine Needles, of which the following is a full, clear, andexact description.

The well-known Mayo knitting-machine needles have applied to their buttsor heels brass bands which cooperate with the grooved cylinder andskeleton frame interposed between the grooved cylinder and camcylinderto prevent the needles from tipping over. These bands by reason ofimperfect fitting or constant usage become loosened from the butts orheels, and when the needles are taken out of the machine to clean thecylinders and for other purposes they drop off, and when the needles arereplaced without the bands on any one or more of the needles suchbandless needles by consequent displacement serve to seriously derangeand often damage the machine.

Many variations in the manner of applying bands to needles have beendevised; but the Mayo construction is perhaps the most economical from amanufacturing viewpoint and therefore this present invention has for itsprimary object a construction of the Mayo band in which the liability toinsecure application and to becoming loosened by usage is greatlyreduced, if not wholly removed.

The invention consists of a knitting-1nachine needle having a bandapplied to its butt or heel and secured thereon by forcing the stockinto the bend between the limbs of the butt or heel.

In the accompanyin drawings, illustrating the invention, in t e severalfigures of which like parts are similarly designated, Figure 1 is a sideelevation, enlarged, of one form of latch-needle. Fig. 2 is a rear viewthereof. Fig. 3 is a side view, greatly enlarged, 0f the butt or heelportion of the needle of Figs. 1 and 2; and Fig. 4 is a rear view ofsame. Fig. 5 is a rear view similar to Fig. Fig. 4, showing one of manymodifications of which the invention is susceptible.

The needle 1, here shown of the latch variety, has its butt or heel 2formed in any usual or approved manner. The wire from which the needleis made is doubled or folded or bent to form the butt or heel, and thereis more or less space between the limbs of this fold or bend, asindicated at 3. The band 4 is of usual form and applied to the butt orheel in any usual way, excepting that its stock is forced down into thespace 3, as at 5, and it is thereby securely locked in place, so as toresist the loosening effect of usage.

As indicated in Figs. 1 to 4, the depression of the stock of the bandinto space 3 maybe effected by a V-shaped punch, the apex pointingrearwardly but other forms of punches may be used. Also, as showninFigs.1 to 4, the stock may be punched down from one side only;

but, as shown in Fig. 5, it may be punched down from opposite sides.Furthermore, this punching down of the stock of the band may be done atother points, the principle of the invention consisting in the lockingof the band upon the butt or heel by displacing its stock externallyinto some cavity in the needle as distinguished from passing the stockof the band through the needle from one side to the other.

What I claim is 1. A knitting-machine needle, having a butt or heel, anda band applied to said butt or heel and locked thereon by punching itsitock in between the limbs of the butt or eel.

2. A knitting-machine needle, having a butt or heel formed by doublingthe wire of the needle upon itself, a band externally applied to saidbutt or heel, and a depression in said band entering the butt or heelbetween its limbs and locking said band in place.

3. A knitting-machine needle of the class described having an endlessband extending around the heel of said needle, said band projecting intoa recess formed in said heel.

4. A knitting-machine needle of the class described having an endlessband extending around the heel of said needle, said band projecting intoa recess between the limbs of said heel.

5. A knitting-machine needle of the class described having a bandextending around the heel of said needle, said band provided with aprojection upon its inner surface proj ecting into a recess formed inthe heel of said needle.

6. A knitting-machine needle .of the class described having an endlessband extending around the heel of said needle, said band inupon oppositesides thereof which project 10 dented upon its outer surface and havinga into a space between the limbs of said heel. projection upon its innersurface formed by In testimony whereof I have hereunto set saidindentation and projecting into a recess my hand this 25th day ofJanuary, A. D. between the limbs of said heel. 1905.
